Available in PDF, EPUB and Kindle. Book excerpt: Seabirds are global travellers connecting oceans and seas all over the world, and facing multiple threats at local and global scales. Seabirds are long-lived top predators, reflecting changes at lower trophic levels, and are good models to assess ecological changes produced by human societies. Thus, world-wide collaborations are needed to understand seabird ecology and to develop effective conservation measures benefitting both humans and seabird populations. This book provides a modern overview on seabird biodiversity studies: it begins by covering the most up-to-date techniques to study seabirds, and then focus on pragmatic issues related with interactions between seabirds and humans, the use of seabirds as ecological indicators and conservation of seabirds. It gives an updated insight on all these topics and highlights gaps that need further development for a comprehensive understanding of the relationships between seabirds and human actions. This book covers the response of the seabird research community to a biodiversity crisis aiming to contribute towards environmental sustainability. It should provide inspiration to a wide range of professionals and students, including the much needed world-wide collaboration between research groups and practitioners. In this way seabird research and conservation provide an inspiration for the solution of global issues such as climate change.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the first detailed biography of Ernst Mayr. He was an ‘architect’ of the Synthetic Theory of Evolution, and the greatest evolutionary biologist since Charles Darwin, influential historian and philosopher of biology, outstanding taxonomist and ornithologist, and naturalist. He is one of the most widely known biologists of the 20th century. Mayr used the theories of natural selection and population thinking as theoretical models within the framework of historical biological studies. He was the first to emphasize the role of biopopulations, thereby pointing out the basic difference between ’population thinking’ and typological essentialism.

Available in PDF, EPUB and Kindle. Book excerpt: For large gulls, predation of other waterbirds is generally considered a specialist strategy and may have potential benefits for reproductive success. During three years of study, however, nearly all herring gulls (Larus argentatus) breeding around the edges of a large ring-billed gull (L. delawarensis) colony on Gull Island, Ontario, were found to eat the chicks of this smaller species to some extent. I collected diet, behavioral, and productivity data to differentiate the extent to which predatory behavior was a specialist strategy or merely opportunistic, test the hypothesis that feeding on waterbirds is evolutionarily beneficial, and evaluate current management strategies in light of the results. Herring gulls predated ring-billed gull chicks most frequently when these chicks were most readily available: immediately after hatching and then again, around fledging when they formed crches on the beach. Herring gulls holding territories close to ring-billed gull crches exploited ring-billed gull prey to a greater extent. Behavioral watches and over 1,900 hours of remote video footage (both day and night) showed that all attacks were initiated within the herring gulls own breeding territories and predatory attacks did not include any specialized behavioral adaptations. Lastly, ring-billed gull chicks appeared to be a relatively poor food item for herring gull chicks and there was no consistent relationship between herring gull productivity and the proportion of ring-billed gull chicks in the diet. I conclude that at this site waterbird predation by herring gulls is predominantly opportunistic and does not appear to show any immediate benefit in terms of evolutionary fitness. This indicates that current management strategies based on controlling specialist predatory gulls are likely to be ineffectual in mixed-species colonies such as this and could be replaced by effective, non-lethal management, such as physical barriers.
